1、混凝土的施工质量问题 (1)现场施工时,混凝土的配合比水灰比不准确。(2)碎石的质量差,石粉、石屑含量过多,搅拌时间不符合《规范》要求,使水泥和骨料不能充分搅拌均匀。按规范规定,应使混凝土表面在湿润的情况下养护一周,而现在大部分采用裸露浇水的办法养护,达不到要求?
1, the quality of construction of concrete problems (1) on-site construction, the ratio of concrete water-cement ratio is not accurate. (2) poor quality of gravel, stone powder, excessive stone content, mixing time does not meet the “standard” requirements, so that the cement and aggregate can not be fully mixed. According to the regulation, the concrete surface should be kept in wet condition for one week, but most of the time, bare watering method is used for curing, failing to meet the requirements.
